As I mentioned in an earlier post, my favorite feature of Scrivener is the ability to differentiate the text the author sees from the text a reader sees. In that post, I described how to separate the two using the "Compile" mechanism, which allows you to control how entire subdocuments appear.
Today I want to go over the feature of Scrivener I use most frequently. It is the ability to separate author's text from reader's text on a sentence-by-sentence level. As before, it is best to follow along in the sample document included here.
